The EVAL-CN0209-SDPZ is an evaluation board described in the circuit from lab CN-0209, entitled "Fully programmable universal analog front end for process control applications". The circuit provides a fully programmable universal analog front end (AFE) for process control applications. The following inputs are supported 2, 3, and 4 wire RTD configurations, thermocouple inputs with cold junction compensation, unipolar and bipolar input voltages, and 4mA to 20mA inputs. Because of the voltage gain provided by the AD8676 and AD8275, the design is particularly suitable for small signal inputs, all types of RTDs, or thermocouples. The AD7193 is a 24bit Σ-Δ ADC that can be configured to have four differential inputs or eight pseudo differential inputs. The ADuM1400 and ADuM1401 provide all the necessary signal isolation between the microcontroller and the ADC. The circuit also includes standard external protection and is compliant with the IEC 61000 specifications.
